One of the largest fraternities is returning to NIU as a changed organization.

Sigma Phi Epsilon (Sig Ep) is recruiting members and hopes to be housed by fall 2013, said Mike Fruchtman, New Chapter Development director.

The fraternity had a chapter at NIU in the past but was suspended after members were involved in a fight in 2007. Police responded but no arrests were made during the incident.

Fruchtman said he thinks the incident occurred because previous Sigma Phi Epsilon members weren't implementing their program "Building Balanced Men" properly. They had the basic skeleton of the program but did not run value workshops.

"There's the Sig Ep of old, which was one of high social stature, but maybe not as high moral character as the Sig Ep we have today," Fruchtman said. "It sounds like they did something stupid. The face of our organization has changed [since then]."

Sigma Phi Epsilon is different than other fraternities because it has the highest GPA of any other fraternity at 3.1, Fruchtman said. Sig Ep also does not have a pledging process. for most fraternities, the pledging process can take anywhere from four to 12 weeks before an individual becomes a member, said Tyler Boggess, Chapter Services director.
